Introduction: Immune-potentiating functions of Lactobacillus plantarum strains in the common carp were evaluated. Material and Methods: Fourteen days of feeding fish dry diet supplemented with the bacteria provided parameters of nonspecific humoral immunity (lysozyme, ceruloplasmin, γ-globulin, total protein levels, and serum bactericidal activity) and cellular immunity (pinocytosis, respiratory burst activity, and potential killing activity of organ phagocytes), as well as the proliferative response of organ lymphocytes stimulated with mitogens. The resistance of fish to infection with Aeromonas hydrophila was also determined. Results: Dietary supplementation with L. plantarum had a substantial influence on the activity of organ phagocytes, especially the potential killing activity of head kidney cells. A significant increase in the proliferative activity of LPS-stimulated B lymphocytes and in the levels of γ-globulins and total protein was observed. The supplemented diet conveyed higher resistance than the control diet as the cumulative fish mortalities after infection with A. hydrophila were 65% and 85%, respectively. Conclusion: The results indicate that dietary supplementation with L. plantarum stimulates the antibacterial resistance of common carp and may reinforce defence against bacterial infections, but further studies need to be conducted.

This study was carried out to evaluate the effects of locally produced fish biosilage as fish meal alternative on feeding, growth efficiency and gut histology in common carp C. Carpio fingerlings. Biosilage was prepared by fermenting marine by-catch fish with date fruit residues, domestic vinegar and citric acid. The produced biosilage was incorporated in feeds to replace 0, 25, 50 or 75% of fish meal protein. Fish were fed for 14 weeks and feeding and growth parameters were close in the four feed groups so as fish survival rate during the experiment (88.9-93.3%). Histological examination of intestine and liver sections has showed improvements when fish fed on the four different feeds. Initial fish group showed signs of nutritional deficiency through limited size of intestinal villi and hepatocytes. However, the histological structure of gut was improved after fish were fed on the experimental feeds without significant differences between fish meal or fish biosilage feeds. The study concluded that fish silage could replace fish meal without adverse effects on feeding, growth efficiency and gut histology.
